Use chemistry to make a real flower glow in the dark. Glowing Flower - Method #1 Test a highlighter pen to make sure it glows under black (fluorescent) light. Yellow is reliable, but some other colors glow brightly, too. Use a knife or saw to cut open the pen and expose the fibers which contain the ink. Remove the ink strip. Squeeze dye from the ink pad into a small amount of water. Trim the end of a flower so that it will be able to take up water. Place the flower in the water with the ink. Allow several hours for the flower to absorb the fluorescent ink. When the flower has taken in the ink its petals will glow under black light. Glowing Flower - Method #2 Would you be surprised to learn that many flowers naturally glow under black or fluorescent light? Some insects, which pollinate the flowers, can see in the ultraviolet. It's usually white flowers that are ultraviolet-colored. You can accentuate the glow of white flowers under a black light by feeding the...

We know DNA. But what is RNA?

We have all heard of DNA. But what exactly is RNA? RNA is similar to DNA in many ways at the structural level however; the differences that are present make RNA chemistry very different than that of DNA. We know DNA. But what is RNA? Almost everyone has heard of DNA and knows the role it plays in heredity. But another extremely important nucleic acid in the cell is RNA. RNA or Ribonucleic acid is similar to DNA in many ways at the structural level. However there are certain differences that are present in RNA chemistry that make it very different than DNA. What is RNA? RNA serves many functions in a cell and is typically a linear polymer that consists of a sugar-phosphate backbone with nitrogenous bases projecting off the backbone. This structure is very similar to DNA. Both of these nucleic acids carry genetic information, which is based on the order of the bases that are present along the chain of the molecule. The presence of a single atomic change in the...

Why do we smell when we sweat?

Why do we smell when we sweat? Sweating can be quite annoying especially since it tends to leave a big wet patch either on your back or under your arms. It makes it especially worse when your sweat tends to smell really foul. Although the bad news is that there is no way to prevent it, the good news is that you can at least tackle it. Why do we sweat? Sweating or perspiration is our body's natural way of cooling us down. We may feel the heat more when we sweat but the truth is that the body is cooling itself by releasing all the built in heat. Our body needs to maintain a normal temperature of 98.6 Fahrenheit failing which we are likely to suffer a heart stroke. Sweat is released through small holes known as pores in our skin. When sweat comes in contact with the atmosphere, it evaporates leaving a cool feeling behind. Sweat is almost made of water with small amounts of chemicals like ammonia, urea, sugar and body salts like sodium . Our body has approxima...
